Mine has a problem with analog TV when the modules are loaded at boot up.  
Reloading them seems to fix the problem.  Try:

#!/bin/sh
#
# unload hdtv wonder modules
#
/sbin/modprobe -r cx8800
/sbin/modprobe -r cx88_dvb
/sbin/modprobe -r nxt200x
/usr/bin/pkill pulseaudio; /sbin/modprobe -r cx88_alsa
/sbin/modprobe -r tuner
/sbin/modprobe -r tuner_simple
/sbin/modprobe -r tuner_types
/sbin/modprobe -r tda9887
/sbin/modprobe -r tda8290
#
# reload hdtv wonder modules
#
/sbin/modprobe cx88_dvb
/sbin/modprobe cx8800 video_nr=1 vbi_nr=1
/sbin/modprobe cx88_alsa index=1


Followed by:

mplayer tv://32 -tv device=/dev/video1:driver=v4l2:chanlist=us-
cable:alsa:adevice=hw.1,0:amode=1:audiorate=48000:forceaudio:volume=100:immediatemode=0:norm=NTSC-
M


Use a channel that is valid in your area.  It works for me.  HTH!
